That's not the point. To me, the point is that _any_ GPU use when a
CPU-only format is invoked is a bug. There should be zero GPU memory
allocation, and zero load on the GPUs.

Can't we do all initial "opening" of anything GPU-related in the
format's init(), if the format is GPU-enabled, and not any sooner?
Perhaps there's some implementation difficulty that I am missing.
Thanks,
